Who completed the first unassisted triple play in a World Series game?

There has only been one unassisted triple play in World Series history. It was turned by Cleveland Indians‘ second baseman Bill Wambsganss in Game Five of the 1920 World Series against the Brooklyn Dodgers. With runners on first and second, Wambsganns leapt to catch Clarence Mitchell‘s line drive, then stepped on second to force one runner, and tagged out the other runner coming from first.
